Unity is a game development ecosystem: a powerful rendering engine fully integrated with a complete set of intuitive tools and rapid workflows to create interactive 3D and 2D content; easy multiplatform publishing; thousands of quality, ready-made assets in the Asset Store and a knowledge-sharing community.

As this game engine grows more and more popular, I think we should make a list of Unity games that have interesting models, which can be imported with my MAXScript - info here and direct download here

Instructions on downloading and extracting games

PC, OSX & Linux - download the game from wherever and the contents should already be available in a Data folder

Android - Since Chrome doesn't allow unverified extensions anymore, the APK Downloader won't work unless you're using Canary.
Luckily there's an easier way with http://apps.evozi.com/apk-downloader/. Simply enter the app URL from Google Play and start the download.
Change the extension from .apk to .zip and extract.Note: some games/apps download additional content after they are installed. Usually it's in the form of .obb files which are just zip archives.

iOS - the only way I know is through iTunes; install it, create an account (preferably US or UK) and browse the store. Downloaded apps are stored in \My Music\iTunes\iTunes Media\Downloads
Change the extension from .ipa to .zip and extract them.Note: some games/apps download additional content after they are installed. I don;t know of any way to get this content without actually installing them.

Xbox 360 - use the usual Xbox tools to extract the game (wxPirs). Files are inside a folder called Media instead of Data

There is of course a list of Unity games on the official website, but it barely scratches the surface.
I'll start with a couple of iOS and Android games and apps designed to showcase different car models. Some are low-poly, others are more than decent.

Porsche and Scion were found by some friends of mine. Google doesn't help much because car manufacturers don't use the terms "3D car configurator".
Your only chance is to sip through official websites and check what configurators they have.

In iTunes and Google Play I usually search for "configurator" "augmented reality" or "360 3D".

Please post any requests or issues with my tools in the appropriate topics.
I'm sorry if I don't reply or if I ignore PMs. My time is very limited.

hehehe well will your friends know some more?
Do you think each web configurator of one brand is the same in each country? For example will Mercedes be the same stuff in Canada, as in Brazil or Austria? I am afraid they ll all have the same configurator, right?

Configurators can be different because in each country there's a different marketing team. That's probably why the Scion configurator is only available in Canada. Also, many AR apps on iTunes are "region locked"
